Plastic pollution is wreaking havoc on marine life, killing or crippling animals underwater. It is estimated that plastic kills 100 million marine mammals each year, with plastic pollution affecting at least 690 marine species, including fish, seabirds, cetaceans, turtles, and many more. Marine animals are dying due to ingestion of plastic, mistaking it for food, or entanglement in plastic-based fishing gear. Microplastics, which are invisible to the naked eye, are easily consumed by wildlife and can adsorb toxins, leading to toxic contamination. Large plastic items can entangle marine mammals, leading to starvation, injury, and vulnerability to predators. The problem of plastic pollution is persistent, as plastic does not decompose but breaks down into deadly microplastics, creating new dangers for marine life.

What You'll Learn
Marine animals mistake plastic for food
Marine animals are swallowing plastic at alarming rates, with nearly 1,800 cases of turtles and marine mammals ingesting plastic objects off the American coast since 2009. The problem is not limited to the American coast, as plastic pollution is a global issue. It is estimated that marine plastics contribute to the death of more than 100,000 marine mammals annually, and this is likely an underestimate as many affected animals are not reported.
Albatrosses, which forage over long distances, often return with plastic instead of their preferred prey. This is because plastic can smell like food to marine animals. For example, algae growing on floating plastic releases dimethyl sulfide (DMS), a compound that attracts foraging birds.
Plastic also feels and sounds like food to some marine animals. For instance, whales and dolphins use echolocation to find prey, but their sonar system cannot distinguish plastic from food. As a result, they may inadvertently consume plastic.
The ingestion of plastic has severe consequences for marine animals. It can obstruct digestion, lacerate intestines, and create a false sense of fullness, leading to starvation. Plastic can also release toxins that accumulate in the fatty tissues of organisms, causing health issues.

Plastic entanglement
Plastic pollution is a pressing issue that poses a significant threat to various species, leading to their decline and even extinction. One of the primary ways plastic causes harm is through entanglement, which occurs when animals become trapped in plastic debris, such as abandoned fishing nets, lines, and other plastic waste. This plastic detritus does not only affect marine animals; it also entangles plants and people, binding them together across diverse geographical locations and global systems.
Large pieces of plastic waste, such as discarded fishing nets and lines, pose a severe risk of entanglement to marine mammals, including dolphins, whales, seals, and sea turtles. These animals can become trapped in the plastic debris, leading to injury, starvation, and increased vulnerability to predators. The entanglement may also restrict their movement, making it difficult for them to find food, shelter, or swim to the surface to breathe, ultimately resulting in death.
Smaller plastic fragments, known as microplastics, also contribute to the entanglement issue. These tiny plastic particles, often derived from larger plastic items that have broken down over time, can entangle smaller marine organisms, such as fish, crabs, coral, and krill. Microplastics are easily ingested by wildlife, including seabirds, as they are invisible to the naked eye. They can cause suffocation, starvation, and toxic contamination as they accumulate in the bodies of affected organisms.
Addressing the issue of plastic entanglement requires a multifaceted approach. Reducing the use of unnecessary disposable plastics, such as cups, plates, cutlery, straws, and shopping bags, is crucial. Additionally, proper disposal and recycling of plastic waste are essential to prevent plastic entanglement and its detrimental effects on various species. By working together to reduce, reuse, and recycle plastic responsibly, we can help mitigate the impact of plastic pollution on the diverse forms of life with which we share our planet.

Plastic pollution in the food chain
Plastic pollution is a pressing issue that affects marine and freshwater organisms. It enters the food chain through fish and other marine animals, causing harm to various species and ultimately impacting human health.
Microplastics, defined as particles smaller than 5mm, are a significant contributor to environmental contamination and food supply pollution. These tiny fragments are invisible to the naked eye, making them easily consumable by wildlife. Microplastics can act as carriers for toxic chemicals, such as pesticides, industrial chemicals, and unintentional pollutants. When ingested, these toxins can transfer to the fatty tissues of organisms, impairing key body functions and causing health issues like allergies, reproductive and hormone problems, immune system disorders, and cancer.
The impact of microplastics on the food chain was demonstrated in a study by student Sarah Nelms. She compared microplastic levels in wild-caught Atlantic mackerel to the scat of captive gray seals they fed on. Nelms found microplastics in half the seal scat and a third of the mackerel, indicating that the mackerel ingested microplastics along with their normal diet of zooplankton, passing it on to the seals. This demonstrates how plastic pollution moves up the food chain.
Moreover, plastic pollution can lead to entanglement and suffocation. Large plastic items, such as abandoned fishing gear, ropes, nets, and lines, can trap marine mammals, fish, and birds, preventing them from escaping, finding food, or reaching the surface to breathe. This entanglement can cause deep flesh wounds, making animals vulnerable to infections and predators even if they are freed.
The number of individual animals affected by plastic is challenging to estimate but likely runs into the billions. Approximately 100,000 marine animals die annually from plastic ingestion or entanglement, and about 1 million seabirds suffer the same fate. Marine mammals like dolphins, sea turtles, sharks, whales, and sea lions are particularly vulnerable to entanglement and ingestion of plastic.

Microplastics and their impact
Plastic pollution in the ocean is a pressing issue that affects marine life in numerous ways. One of the most significant concerns is the presence of microplastics, which are plastic particles smaller than 5 millimetres that come from the degradation of larger plastics. These microplastics have far-reaching impacts on marine species, wildlife, and even humans.
Marine animals, such as seabirds, turtles, dolphins, whales, and fish, often mistake small plastic fragments floating on the water's surface or resembling their prey for food. These ingested plastics can lead to starvation, suffocation, and toxic contamination as they accumulate in the food chain. Microplastics, being invisible to the naked eye, are easily consumed by wildlife and can absorb toxins, transferring them to the fatty tissues of the organisms that ingest them. This has been observed in various fish species, including commonly consumed fish by humans, indicating potential health risks for people who eat contaminated seafood.
Beyond ingestion, marine mammals also face the threat of entanglement in abandoned fishing gear, such as nets, lines, and six-pack rings. This entanglement can lead to drowning, difficulty in finding food and shelter, and increased vulnerability to predators. The impact of plastic pollution is not limited to marine species; land animals, such as deer, camels, and elephants, have also succumbed to ingesting plastic debris, highlighting the widespread reach of plastic pollution.
The impact of microplastics extends beyond the immediate harm caused to individual organisms. Microplastics have been detected in various environmental samples, including drinking water, honey, beer, milk, and soft drinks, and seafood. Humans are potentially exposed to microplastics through oral intake, inhalation, and skin contact. The health hazards associated with microplastics are a growing concern, with studies indicating potential toxic effects, including oxidative stress, DNA damage, organ dysfunction, metabolic disorders, immune response, neurotoxicity, and reproductive issues. Additionally, microplastics may act as carriers for other pollutants, such as antibiotic-resistant bacteria and pathogens, further exacerbating their impact on biological systems.
While the long-term impacts of microplastics are yet to be fully understood, the ubiquity of these particles in the environment and their detection in human samples underscores the urgency of further research and regulation. Reducing plastic manufacturing, increasing recycling efforts, and advocating for sustainability are essential steps in mitigating the harmful effects of microplastics on both ecosystems and human health.

Human impact and prevention
Human activities have led to an unprecedented amount of plastic pollution, which has had a devastating impact on the environment and wildlife. Plastic pollution in the oceans has increased significantly due to human negligence, with an estimated 8 to 10 million tons of plastic entering the water each year. Marine species are the most affected by plastic pollution, with over 690 marine species impacted, including fish, seabirds, cetaceans, turtles, and many more.
One of the primary ways plastic kills marine animals is through ingestion. Marine animals mistake plastic for food, leading to issues such as starvation, suffocation, and toxic contamination. Sea turtles, for example, often consume plastic bags, believing them to be jellyfish or seaweed. Similarly, seabirds scoop up small plastic fragments along with small fish and algae, leading to digestive tract obstructions and internal organ punctures. Large whales are also affected, with a juvenile sperm whale dying from inflammation caused by ingesting 30 kilograms of plastic.
Entanglement in plastic is another significant cause of death for marine animals. Abandoned fishing gear, nets, and lines trap and entangle various marine creatures, including dolphins, sea turtles, sharks, and whales. These animals can drown or suffer severe injuries, making them vulnerable to predators.
Plastic pollution also affects land animals, such as deer in the UK and Japan, who have been found dead with plastic in their stomachs. Arabian camels are another example, with half of the population dying annually from ingesting plastic bags.
To prevent further harm and species death due to plastic pollution, it is crucial to reduce plastic consumption and properly dispose of plastic waste. Recycling and reusing plastic products can help reduce the amount of plastic entering the environment. Additionally, avoiding single-use plastics, such as disposable cups, plates, cutlery, straws, and shopping bags, can significantly reduce plastic pollution. It is also important to support initiatives focused on cleaning up existing plastic pollution, such as the Great Pacific Garbage Patch, and to advocate for policies that promote sustainable practices and reduce plastic waste.
While the full extent of the impact of plastic pollution may never be known, it is clear that human activity and negligence have had a devastating impact on countless species. It is our responsibility to take action and prevent further harm to the environment and the diverse species that depend on it.
